Materials Guide – Broken Blade Wiki
Weapon pieces, element materials, boss drops, and utility reroll items — what each category does and where to farm it.
By Bloxron Editorial Team · Last updated
Overview
Materials unlock weapons, finish forge routes, and fuel rerolls. Farm them from chests, bosses, Sky Spire, and milestone redeem codes. Capstone routes split three ways: Holy Grails for Excalibur, Sacrifice Pieces from Guts for Dragon Slayer, and code drops such as Truth Scroll, Void, and Arkenstone for high-tier crafts and Weapon Ascension. The weapons guide maps each drop to a weapon line.
Four Material Categories
| Category | Function | When you need it |
|---|---|---|
| Weapon Pieces | Unlock weapon types | First time you open a new weapon line |
| Element Rerolls | Roll passive Element buffs | Level 500+ — see Elements guide |
| Boss Materials | Unlock advanced weapons | ★★★ and ★★★★ weapons |
| Utility Materials | Rerolls and access items | Rerolls and boss access |
Weapon Pieces
| Type | Unlocks |
|---|---|
| Sword Pieces | Sword weapon line |
| Katana Pieces | Katana weapon line |
| Buster Pieces | Buster weapon line |
Drop locations are on the bosses guide. See the weapons guide for which line you are building.
Elements & Element Rerolls
Character Elements (Fire, Thunder, Wind, Life, Earth, Water) are passive combat buffs rolled with Element Reroll items at level 500. They stack and are separate from weapon crafting materials.
Tier list and stacking rules are on the Elements guide. Boss drop rates are on the bosses guide.
Boss Materials
| Material | Used for |
|---|---|
| Sacrifice Piece | Dragon Slayer and other top-tier Buster paths |
| Moon Piece | Moon Cut katana evolution |
| Eye Patch | Explosion Buster craft on Explosion Island |
| Holy Material | Forge Master ore upgrades on Muspelheim — not used for Excalibur |
Where to farm
Boss-specific drop tables and respawn timers are on the bosses guide. Sacrifice Piece comes from Guts on Explosion Island; Red Orbs from Space Invaders on Midgard Island; Moon Piece from Nidavellir raids.
Endgame Materials
Capstone weapons and Ascension pull from a second material layer beyond boss reroll farming. Farm routes live on the bosses guide.
| Material | Used for | Source |
|---|---|---|
| Truth Scroll | Capstone weapon forging — Dragon Slayer and high-tier upgrade paths | Milestone redeem codes and late-game rewardsStock before a Dragon Slayer or endgame craft push |
| Void | Capstone weapon forging — paired with Truth Scroll on top-tier routes | Milestone redeem codes and late-game rewardsOften bundled with Truth Scroll in code drops |
| Holy Grail | Excalibur craft at the Jotunheim tower forge | Sky Spire floors 41+ — rate climbs on higher floorsSeparate from Holy Material ore dropped by Jotunheim guardians |
| Arkenstone | Weapon Ascension and Breakthrough rolls | Milestone redeem codes and late-game rewardsRedeem active codes before a craft or ascension push |
| Soul Ore | Ascension-era upgrades and high-floor progression | Sky Spire floors 101–200 and Charon farmingStack early — new ores usually feed the next weapon upgrade tier |
| Space Ore | Yamato upgrades after the initial craft | Space Invader drops on Midgard Island or Space Shop (Holy Coins)Not the same item as the Space forge element required to craft Yamato |
| Soul Stone | Soul Forge levels on Jotunheim | Jotunheim guardians and Sky Spire clears |
| Sky Key | Sky Spire floor attempts | Jotunheim guardian rotation — guaranteed drops on the four elemental bosses |
Utility Materials
| Item | Function |
|---|---|
| Race Reroll | Change character race (usable at Lv.500) — see Races guide |
| Element Reroll | Change elemental affinity |
| Blessing Reroll | Re-roll passive bonuses (usable at Lv.1000) — see Blessings guide |
| Boss Key | Access locked boss encounters |
| Boss Coin | Exchange for boss rewards |
None of these raise raw damage directly, but rerolls and boss access save time on the way to your target weapon.
FAQ
What are materials used for in Broken Blade?
Unlocking weapons (weapon pieces), crafting and forging (boss and element materials), and rerolls (Race, Element, Blessing). You need specific materials at each step — they are not optional side loot.
How do you get weapon pieces?
Chests, regular enemy farming, and boss encounters. Sword, Katana, and Buster pieces are separate — you only need the type matching the weapon line you are pursuing.
What is the difference between Elements and boss materials?
Elements (Fire, Thunder, Wind, etc.) are passive buffs from Element Rerolls — see the elements guide. Boss materials (Sacrifice Piece, Moon Piece, Eye Patch) unlock specific weapons like Dragon Slayer, Moon Cut, and Explosion. Excalibur uses Holy Grails from Sky Spire.
Do utility materials increase combat power?
No direct damage boost. Reroll items change your race, element, or blessing. Boss Key and Boss Coin open encounters that drop crafting materials.
What are Truth Scroll and Void used for?
Capstone forging materials for Dragon Slayer and other high-tier weapon routes. Milestone redeem codes are the fastest way to stock your first batch — see the codes page.
How do I get Truth Scroll and Void?
Milestone redeem codes are the fastest source — check the codes page for active entries. Both materials feed Dragon Slayer and other capstone forge routes; pair them with Sacrifice Pieces from Guts on Explosion Island.
What is the difference between Holy Material and Holy Grail?
Holy Material is ore from Jotunheim guardians used in general forging. Holy Grail is a Sky Spire drop from floor 41 onward — you need a large stack specifically for Excalibur.
What is Arkenstone used for?
Weapon Ascension and Breakthrough rolls after Soul Forge 12. Active milestone codes are the fastest way to stock your first batch — see the codes page.
